FAUCET SUPPORTING PLUG Filed Feb. 2, 1929 I N VEN TOR Patented Nov. 11, 1930 UNITED stares ISAAC '1. KAHN, OF CLEVELAND, OHIO, ASSIGNOR TO THE CONSOLIDATED IRON-STEEL I MANUFACTURING COIMPANY, OF CLEVELAND,-.OHIO, A: CORPORATION OF OHIO nAUoE'r-sUProRTING PLUG Application filed February 2 This invention relates to improvements in faucet supporting plugs, and has for its object the provision of a leakproof, cast metal plug for closing a hung opening and interiorly supporting a faucet within the associated barrel or drum.

Various types of plugs previously have been provided with faucet supporting means, a typical plug of this type being shown in Patent No. 1,467,698, issued to Owen Thomas. It has been found that screw plugs having suitable attaching means cast integrally of said plugs are not invariably leakproof with respect to high volatile liquids, particularly, such as gasoline or alcohol. Not infrequently leakage develops through the bodies of the plugs, and more particularly the diaphragm portions thereof. After careful investigation and experiment, I have ascertained that 29 these diaphragm portions have been structurally weakened and rendered relatively porous in a fair percentage of prior cast metal plugs.

Accordingly, I have sought to overcome. 25 this difficulty and produce a cheap, yet efficient cast metal plug by so modifying the metallic body or cross section and the attaching means as to avoid cooling stresses and deterioration in the metal ofthe plug, as will be explained in connection with the accompanyino drawings illustrating a preferred type o plug in comparison with one of the prior art. In the attached drawings:

Fig. 1 is a cross section of a screw plug exhibiting the improved faucet attaching means and disposition of the metal in accord ance with the instant invention;

Fig. 2 is an exterior plan view, thereof;

Fig. 3 is an interior plan view thereof, and

Fig. 4 illustrates the plug with an attached faucet and the container, partially in elevation and partially in section.

Throughout the several figures of the Hi drawings, I have employed the same character of reference to indicate similar parts.

The plug of Fig. 1 is shown sectionally in order to emphasize the features of the invention and assist in explaining the remedied defects of the former types of plug.

Thus, the plug of the prior art is provided with a flanged body portion having a relatively heavy annular cross section exteriorly threadedand interiorly threaded, adapted to screw into the bung opening, and to accommodate the threadeclend of a faucet. It will.

that the leakage referred to occurs.

Careful investigation has shown that this diaphragm area being surrounded} by the much heavier, annular portions is subjected to such stresses up'onthe cooling of the metal, that the diaphragm of the plug, is frequently rendered unreliable for retaining the liquid contents of a container against minor leaks tributed to, as well as fires.

Y Referring particularly to Figs. 1 and 3,,it will be seen that the annular flanged attach; ing member body portion 0,0, is of' much lighter annular cross section than the construction: of the prior art, while the diaphragm d comprises a thickened central area age, so thataccidents from explosion, are cond and three adjacent thinner areas d, flanking the lugs 'e separated approximately by 100 arcs. These lugs are of substantial height and are provided with an interrupted thread 6. for accommodating the threaded This radical'distribution of the metaland separation of the faucet-supporting lugs permits, the casting of screw plugs which safely maybe used. to displacethe present forged plugs of the art, with a material attendant saving. It is found that the diaphragm portion, c l", d, of my'improved screw plug. is not unduly stressed in casting and cooling;

particularly as the heavy surrounding annularportion above the flange is dispensed with, wh le even better attaching meansare provided for the faucet.
